Method for chasing animals from a location

Abstract

This invention provides for a method of keeping animals away from a location comprising subjecting the location to a light beam or subjecting the animals to the light beam. Also provided for is a method for disturbing the nocturnal nesting areas of water fowl by subjecting those nocturnal nesting areas to a light beam.

The embodiment of the invention in which an exclusive property or privilege is claimed is defined as follows:  
     
       1. A method for chasing animals away from a surface the animals are traversing, the method comprising subjecting the surface to a fixed laser beam having a wavelength selected from between approximately 4.000 and 7.500 Angstroms and wherein the laser beam is positioned between approximately 8 and 24 inches above the surface so as to effect a laser swath parallel with the surface. 
     
     
       2. The method as recited in  claim 1 , wherein the surface is defined by a body of water. 
     
     
       3. The method as recited in  claim 1 , wherein the laser beam has a wavelength selected from between approximately 6450 and 6650 Angstroms. 
     
     
       4. The method as recited in  claim 1 , wherein the laser beam has an intensity of at least 20 μW/cm 2  at 400 meters from a light beam source. 
     
     
       5. The method as recited in  claim 1 , wherein the laser beam is emitted with a swath of approximately 90°. 
     
     
       6. The method as recited in  claim 1 , wherein the surface is subjected to a plurality of laser beams. 
     
     
       7. The method as recited in  claim 1 , wherein the animals are water fowl, the surface is the surface of a water body, and the water fowl are swimming on the surface. 
     
     
       8. A method for keeping animals from a surface, comprising subjecting the animals to a fixed visible laser beam swath positioned between approximately 8 and 24 inches above the surface so that the swath is parallel with the surface. 
     
     
       9. The method as recited in  claim 8 , wherein the surface is defined by a body of water. 
     
     
       10. The method as recited in  claim 8 , wherein the laser beam swath has an intensity of at least 20 μW/cm 2  where the animals are located. 
     
     
       11. The method as recited in  claim 8 , wherein the laser beam swath spans approximately 90°. 
     
     
       12. The method as recited in  claim 8  wherein the animals are located within the laser beam swath. 
     
     
       13. The method as recited in  claim 8 , wherein the laser beam swath is visible by the animals. 
     
     
       14. A method for disturbing nocturnal nesting areas of waterfowl, said method comprising: 
       a) selecting a nocturnal nesting area; and  
       b) subjecting said nocturnal nesting area to a single-wavelength laser beam swath wherein the laser beam is positioned between approximately 8 and 24 inches above a water surface near the nesting area so as to effect a laser swath parallel with the nesting area.  
     
     
       15. The method as recited in  claim 14 , wherein the laser beam swath has a wavelength of between approximately 4,000 and 7,000 Angstroms. 
     
     
       16. The method as recited in  claim 14 , wherein the laser beam swath has an intensity of at least 20 μW/cm 2  at 400 meters from a light. 
     
     
       17. The method as recited in  claim 14 , wherein the laser beam swath is emitted within an angle of approximately 90°. 
     
     
       18. The method as recited in  claim 14 , wherein the laser beam swath is activated at dusk. 
     
     
       19. The method as recited in  claim 14 , wherein the laser beam swath is emitted from a fixed source.
